My house due to the space, the walls and all the devices definitely needs mesh or extenders and I find mesh to be more reliable. I don't need massive speed increases. Fiber around me is 1k up and down where Spectrums top plan is 100 download and 10 upload. There are times when we try to watch Plex and it buffers so much it makes it a hassle. These are tri-band compared to my dual-band, cover more area and produce higher speeds when we switch from Spectrum to ATT Fiber here shortly. If we can get 300+ down and 25+ upload it'll make our connected house run smoothly. And that is all I can ask for until Wifi 6 becomes mainstream.I tried them but found them to be slower than my Comcast TG3482G and Asus RT-AX88U. I can get ~200 Mbps, ~500 Mbps and ~750 Mbps respectively (next to the router, up to ~650 Mbps at 30 feet upstairs) although very variable as normal for WiFi. I live in a compact area so I get by with just the single router.
The Asus might work in larger environments as I see that it supports AIMesh.
